The better and cheaper X1. The Lenovo ThinkPad X1 Carbon G6 has joined its WQHD HDR and Core i7 equipped sibling in our offices for review. The G6 is the entry-level model of current touchscreen-equipped Carbon X1 devices. The G6 is free from the thermal issues from which its sibling suffered thanks to its less powerful CPU, but this comes at a cost to the WQHD HDR display. Despite this drawback, the G6 provides a more rounded overall experience than its more expensive sibling.
